Abstract
La présente invention concerne une structure de polyamides non tissés ayant des propriétés antimicrobiennes comprenant : des fibres de polyamides non tissés comprenant moins de 4 000 ppm de zinc dispersées dans les fibres de polyamides non tissés; et moins de 2 000 ppm de phosphore. Les fibres ont un diamètre moyen de fibre inférieur à 25 microns; et la structure de polyamides présente une réduction de Staphylococcus Aureus d'au moins 90 %, telle que mesurée par ISO 20743-13.
